NASA astronaut Christina Koch said the Artemis II crew had to improvise after the onboard toilet malfunctioned early in their mission [1, 2].

This failure highlights the critical nature of life-support systems during deep-space exploration. While the mission successfully orbited Earth, a plumbing failure in a confined capsule creates immediate sanitary and psychological challenges for astronauts.

The incident occurred during the Artemis II flight, which launched in May 2024 [2]. The four-member crew [1] operated from within NASA’s Orion crew capsule. Koch said the waste-collection system stopped working due to a plumbing failure, forcing the team to find alternative methods to manage waste [1, 2].

Koch discussed the experience during an interview with CBS Mornings. She said that while some aspects of space travel are luxurious, basic utility failures are more disruptive. "Showers in space are great, but a broken toilet is a real challenge," Koch said [1].

The plumbing issue became a point of public interest during the early days of the mission [2]. Despite the technical setback, the crew remained operational. When asked about how they handled the lack of a functioning toilet, Koch said, "We made do" [1].

NASA's Orion capsule is designed to sustain humans for extended periods away from Earth. The failure of a primary waste system during a crewed test flight provides essential data for engineers. This allows the agency to refine hardware before attempting longer-duration missions to the moon.

“"We made do."”

The malfunction of a basic utility like a toilet on the Artemis II mission underscores the volatility of hardware in the space environment. For NASA, these failures are critical learning opportunities; solving plumbing issues in the Orion capsule is a prerequisite for the Artemis program's goal of returning humans to the lunar surface, where improvisation is less viable than on an Earth-orbiting mission.
